1 Make Your Own OS Image
1.1 Setup Development Environment
In order to compile an Android image we suggest you do it on a 64 bit Ubuntu 16.04 system and install the following packages:
sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip sudo apt-get install flex curl libncurses5-dev libssl-dev zlib1g-dev gawk minicom sudo apt-get install openjdk-8-jdk sudo apt-get install exfat-fuse exfat-utils device-tree-compiler liblz4-tool
For more details refer to https://source.android.com/source/initializing.html;
Or you can do it in Docker: friendlyelec-android-docker
1.2 Install Cross Compiler
1.2.1 Install aarch64-linux-gcc 6.4
This compiler can be used to compile a Linux kernel and u-boot. You can do it by running the following commands:
git clone https://github.com/friendlyarm/prebuilts.git sudo mkdir -p /opt/FriendlyARM/toolchain sudo tar xf prebuilts/gcc-x64/aarch64-cortexa53-linux-gnu-6.4.tar.xz -C /opt/FriendlyARM/toolchain/
Add the compiler's directory to the PATH variable by appending the following lines to the ~/.bashrc file:
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin:$PATH export GCC_COLORS=auto
Run the ~/.bashrc script to make it effective in the current commandline. Note: there is a space after ".":
. ~/.bashrc
This is a 64 bit compiler and cannot work on a 32 bit Linux system. You can test if your compiler is installed correctly by running the following commands:
aarch64-linux-gcc -v Using built-in specs. COLLECT_GCC=aarch64-linux-gcc COLLECT_LTO_WRAPPER=/opt/FriendlyARM/toolchain/6.4-aarch64/libexec/gcc/aarch64-cortexa53-linux-gnu/6.4.0/lto-wrapper Target: aarch64-cortexa53-linux-gnu Configured with: /work/toolchain/build/aarch64-cortexa53-linux-gnu/build/src/gcc/configure --build=x86_64-build_pc-linux-gnu --host=x86_64-build_pc-linux-gnu --target=aarch64-cortexa53-linux-gnu --prefix=/opt/FriendlyARM/toolchain/6.4-aarch64 --with-sysroot=/opt/FriendlyARM/toolchain/6.4-aarch64/aarch64-cortexa53-linux-gnu/sysroot --enable-languages=c,c++ --enable-fix-cortex-a53-835769 --enable-fix-cortex-a53-843419 --with-cpu=cortex-a53 ... Thread model: posix gcc version 6.4.0 (ctng-1.23.0-150g-FA)
1.3 Compile Android8.1 Source Code
1.3.1 Download Android8.1 Source Code
There are two ways to download the source code:
- repo archive file on netdisk
File location on netdisk:sources/rk3399-android-8.1.git-YYYYMMDD.tgz (YYYYMMDD means the date of packaging)
After extracting the repo package from the network disk, you need to execute the sync.sh script, which will pull the latest code from gitlab:
tar xvzf /path/to/netdisk/sources/rk3399-android-8.1.git-YYYYMMDD.tgz cd rk3399-android-8.1 ./sync.sh
- git clone from gitlab
{{{1}}} source code is maintained in gitlab, You can download it by running the following command:
git clone https://gitlab.com/friendlyelec/rk3399-android-8.1 --depth 1 -b master
1.3.2 Generate Image File
You can compile an Android source code and generate an image file:
cd rk3399-android-8.1 ./build-nanopc-t4.sh -F -M
1.3.3 Update System with New Image
After compilation is done a new image file will be generated in the "rockdev/Image-nanopc_t4/" directory under Android 8.1's source code directory. You can follow the steps below to update the OS in {{{1}}}:
1) Insert an SD card which is processed with EFlasher to an SD card reader and insert this reader to a PC running Ubuntu. The SD card's partitions will be automatically mounted;
2) Copy all the files under the "rockdev/Image-nanopc_t4/" directory to the SD card's android8 directory in the "FRIENDLYARM" partition;
3) Insert this SD card to {{{1}}} and reflash Android

1.4 Compile Android7 Source Code
1.4.1 Download Android7 Source Code
There are two ways to download the source code:
- repo archive file on netdisk
File location on netdisk:sources/rk3399-android-7.git-YYYYMMDD.tgz (YYYYMMDD means the date of packaging)
After extracting the repo package from the network disk, you need to execute the sync.sh script, which will pull the latest code from gitlab:
tar xvzf /path/to/netdisk/sources/rk3399-android-7.git-YYYYMMDD.tgz cd rk3399-nougat ./sync.sh
- git clone from gitlab
{{{1}}} source code is maintained in gitlab, You can download it by running the following command:
git clone https://gitlab.com/friendlyelec/rk3399-nougat --depth 1 -b nanopc-t4-nougat
1.4.2 Generate Image File
You can compile an Android7 source code and generate an image file:
cd rk3399-nougat ./build-nanopc-t4.sh -F -M
1.4.3 Update System with New Image
After compilation is done a new image file will be generated in the "rockdev/Image-nanopc_t4/" directory under Android7's source code directory. You can follow the steps below to update the OS in {{{1}}}:
1) Insert an SD card which is processed with EFlasher to an SD card reader and insert this reader to a PC running Ubuntu. The SD card's partitions will be automatically mounted;
2) Copy all the files under the "rockdev/Image-nanopc_t4/" directory to the SD card's android8 directory in the "FRIENDLYARM" partition;
3) Insert this SD card to {{{1}}} and reflash Android
Here is an alternative guide to update OS: sd-fuse_rk3399
1.5 Compile FriendlyCore/FriendlyDesktop/Lubuntu/EFlasher Kernel Source Code
git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-linux-v4.4.y kernel-rockchip cd kernel-rockchip make ARCH=arm64 nanopi4_linux_defconfig export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH make ARCH=arm64 nanopi4-images
After compilation is done a kernel.img and a resource.img will be generated. You can simply copy them to replace the existing files in your eflasher SD card. We assume your SD card's FRIENDLYARM partition is mounted at the FRIENDLYARM directory and you can run the following commands to update system:
# for Lubuntu cp kernel.img resource.img /media/FRIENDLYARM/lubuntu/ # for FriendlyCore cp kernel.img resource.img /media/FRIENDLYARM/friendlycore-arm64/ # for FriendlyDesktop cp kernel.img resource.img /media/FRIENDLYARM/friendlydesktop-arm64/
Or you can use a USB Type-C cable and the Linux_Upgrade_Tool utility to update system.
1.6 Compile FriendlyCore/FriendlyDesktop/Lubuntu/EFlasher U-boot Source Code
git clone https://gitlab.com/friendlyelec/rk3399-nougat --depth 1 -b nanopc-t4-nougat cd rk3399-nougat/u-boot make CROSS_COMPILE=aarch64-linux- rk3399_defconfig export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH make CROSS_COMPILE=aarch64-linux-
After compilation is done a uboot.img, a trust.img and a rk3399_loader_v1.12.109.bin will be generated. You need to rename the rk3399_loader_v1.12.109.bin to "MiniLoaderAll.bin" and copy it to replace the existing file in your eflasher SD card. We assume your SD card's FRIENDLYARM partition is mounted at the FRIENDLYARM directory. You can run the following commands to update system:
# for Lubuntu cp uboot.img trust.img /media/FRIENDLYARM/lubuntu cp rk3399_loader_v1.12.109.bin /media/FRIENDLYARM/lubuntu/MiniLoaderAll.bin # for FriendlyCore cp uboot.img trust.img /media/FRIENDLYARM/friendlycore-arm64 cp rk3399_loader_v1.12.109.bin /media/FRIENDLYARM/friendlycore-arm64/MiniLoaderAll.bin # for FriendlyDesktop cp uboot.img trust.img /media/FRIENDLYARM/friendlydesktop-arm64 cp rk3399_loader_v1.12.109.bin /media/FRIENDLYARM/friendlydesktop-arm64/MiniLoaderAll.bin
Or you can use a USB Type-C cable and the Linux_Upgrade_Tool utility to update system.
